[0 at whom it may concern:

Be it known that T, BEs'rnn Wnssrnn, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented a'certain new and useful improvement in Tabulating- Machines, of which the following is a specification. 1 v

This application is a continuation in part of my application Serial Number 564,795, filed June 3, 1910.

My invention relates to tabulating machines, and is intended particularly for the easier listing of numbers.

The invention is illustrated by the draw ings accompanying this specification.

Of these, Figure 1 shows an end elevation of a typewriter of the Remington visible style, and Fig. 2 shows a front elevation of the same.

Mounted upon typewriter is the carriage 2. This contains the platen 3 upon which the paper is mounted as usual, and fed upward by means of the ordinary paper feed lever 4. Mounted upon the back of the carriage is a tabulation bar 5 upon which may be mounted one or more tabulator stops 6. These stops are intended to cooperate with the tabulator rods 7 which are operated by the links 10. each connected at its one end to a tabulator rod 7 and at its other end to one of a series of bell-crank levers 9. Cooperating with these levers are a set of rods 42, each of them pro vided at its front end with a finger piece 40, whereby it may be easily manipulated, and supplied with a collar 41 fastened thereto, and cooperating with the levers mentioned above. Of course, the machine includes keys, type levers, type bars, and other mechanisms, but as they form no part of my-in- Vention, and as their presence in the drawings would tend to confuse rather than elu cidate, they have been left out.

Fastened to the carriage 2 of the typewriter is a typewriter rack 50 pivotally mounted upon studs 52. This rack codperates with the escapemcnt gear 53, as is usual. In its normal position on the typewriter, the

rack 50 is in mesh with the escapement gear 53 which escapement gear therefore prevents the rack and carriage attached thereto from advancing to the left. But in the operation the framework 1 of thecarriage of the typewriter.

" provided at its upper end with finger pieces.

of the tabulator, it is necessary that the care riage should advance to the left without anv nterference from the escapement, and this 15 accomplished by disconnecting it from the escapement gear 53. This is accomplished through the intermediation of a'bar mounted in' front of all of the tabulator rods 7 and supported at its ends by two side pieces 61 pivotally mounted upon studs .62 in the framework. From one of the side pieces 61 there extends an arm 63 which rests upon an arm 64 of lever 65, pivotally supported at its fulcrum 66 and having an other arm 67 hearing under the rack 50 before mentioned.

The operation of any of the tabulator finger pieces 4:0 and the consequent protrusion of the connected tabulator rod 7 therefore results in the -swinging of the bar 60 about the studs 62, and the consequent rotation of lever'65, and the lifting up of the rack 50. The rack 50 is thus lifted away and disconnected from the escapement gear 53, and the carriage is thus free to move in either direction without any interference from the escapement. Normally the carriage has a tendency tomove to the left which tendency is imparted to it by the tension spring drum pulley and strap as is usual.

In the drawings, 70 represents the spring pulley and 7f the strap. This strap is connected to an extension 72 fastened to the So far, all the mechanism that has been deiscribed is old, and differs in no way from that which is on the market at present. and therefore will not he further entered into here. The new features of my invention will now be taken up.

Mounted upon the framework, are another set of retracting tabulator keys 8, each Coiiperating with each retracting tabulator key 8 is an arm 31, and all of these arms are rigidly fastened to a shaft 30 pivotally mounted in the framework. Fastened at one end to the shaft 30 and at its other end to the framework of the machine is a spring 35 which tends. to hold the arms 31 in an elevated position. At one end of shaft 30is rigidly fastened an arm 32 which is connected to one end of a link whose other end is connected to a three-waystop cock 24 therefore enters the cylinder and pushes at one end of cylinder 20. This cylinder is fastened upon the framework, and its cock is connected by a tube notshown in the illustratipn-to a'compressed air reservoir, Slid-v ing 1n the cylinder 20 is a piston 21 which has extending therefrom a rod 22 connected at its other endto an arm 23 Which'is ri'gidly fastened to the paper feed lever above mentioned. I

-The depressing of any of the retracting keys 8 results in the depressing of the cooperating arm 31, and the consequent rotating of shaft againstthe force of spring 35, and the opening of the three-Way cock '24 to the compressed air reservoir. The air 1 The, depressing of the tabulator key there fore. results. not only in the retracting of the carriage to the right, but also in the protruding of the tabulator rod 7 in the path of the tabulator stop 6. The carriage therefore moves to the ri 'ht under the influence of the compresse air as far as it can, namely, until the tabulator stop 6 strikes the protruding tabulator rod 7 Where the carriage necessarily comes to rest. As long as the operator retains his finger upon the retracting tabulator key 8, the carriage remains With its tabulator stop 6 pressing against the protruding tabulator rod 7. But as soon as the operator removes his finger from the retracting tabulator key 8, it rises under the influence of'its spring 1:2. This removes the pressure from the cooperating arm 31 and the shaft 30 under the influence of its spring 35 therefore rotates and closes the threeway valve 24 to the compressed air reservoir, and simultaneouslv opens the inside of the cylinder 20 to the outside air. The compressed air pressure inside of the cylinder is therefore released. Simultaneously the pressure has been released from the tabulator rod 7, which is 4 7 therefore retracted and removed out of the Way of the stop 6. It Will therefore be seen that by means of this mechanism the operator has at his command two sets of tabulator keys, the advancing tabulator keys 40, the operation of which advances the carriage to y the left, and the retracting tabulator keys 8 the operation of which retracts the carriage to the right. Advancing tabulator keys have'been on the market for a long time.

They are employed to a great extent for the listing of numbers in a horizontal line; The

, retracting 'tabulator keys 8 find one of their uses. in the listing of numbers arranged. in a vertical.,.column underneath each other. The operation is as" follows. After the units figure of -a-number has been typewritten, I l

the operator depresses the retracting tabu? lator key" 8 correspondingto the highest Havi'ngthus described my invention, I
